This status is then communicated to the upstream Nagios server, which uses the results to monitor the current status of the distributed network. Each console server is preconfigured with checks that are part of the Nagios plug-ins package: check_tcp and check_udp are used to check open ports on network hosts. check_ping is used to check network host availability. check_nrpe is used to execute arbitrary plug-ins in other devices. Each console server is preconfigured with two checks that are specific to Tripp Lite: check_serial_signals is used to monitor the handshaking lines on the serial ports. check_port_log is used to monitor the data logged for a serial port. 192
